% python setup.py timeit This would run timeit functions in timings.py. Features Lets you write your timing test code as regular code instead of strings, but without the overhead of a function call. Put your timing test code in a module or inside a function Uses the

Python decorator to measure the execution time of …

To overcome this, created the @timeit decorator which allows you to measure the execution time of the method/function by just adding the @timeit decorator on the method. @timeit decorator:

How to Performance Test Python Code: timeit, cProfile, …

To test code using the timeit library, you’ll need to call either the timeit function or the repeat function. Either one is fine, but the repeat function gives a bit more control. As an example, we’ll test the following code snippet from an earlier article on list:

A Guide to Python’s pow() Function
When deciding between using the pow() function or the ** operator, the most important factor to consider would be the efficiency of your code. We can use the timeit.timeit() function from the timeit module to find out how fast Python executes our code.

Python timeit module With Examples
Python timeit When a program is executing, many background processes also run to make that code executable. The time module doesn’t take those processes into account. If you need precise time performance measurements, timeit is the module to go for. The timeit module runs a piece of code 1 million times (default value) and takes into account the minimum amount of time it took to run that
Python: Timing Functions with timeit
This page shows you how to use timeit module for timing the speed of a function that has one or more parameter. Suppose you have 2 functions f1, f2, with different implementations. You want to see the speed of f1, f2, when the argument is huge. mydata

Start Using The timeit Library in Python!

All we did was to pass the code as a string and specify the number of iterations to the timeit.timeit function. Now let us look at a way to use this amazing library to compare two functions. For this example, let us compare two sorting functions, one is a simple bubble sort, and the other is the Python’s built-in sorted() function.
